coupling 3.

Heretofore in the art it has sometimes been the cusvent the clots ofparticles of foreign matter from re n-chiom to utilize platinumstrainers and spinnerels due to the resistant chemical qualities ofplatinum. In utilicing hard rubber, however, it is obvious that the costis reduced many fold and at the sometime the spinnerets may be inadethin enough to enable the niinutelike vperforations to be drilledtherein. having predeterruined and uniform diameters, I have found thatspinncrets a'nd strainers inade oi thin hard rubber or similar rnaterialare sufliciently strong to with-stand the great pressureoi the viscousfluid without becoming distorted. The thin hard rubber spinner-ct andstrainer. flanged as illustrated and described, will act to securethemselves more firmly in position in the spinning head by virtue of theheavy pressure of the viscous fluid againstiheir inner faces, causingthe same to be put nnder'tension.

which tension is transferred to the flanges. thus tightening the sameagainst the tapering interior surface of the rings 8 and 12.respectively. v

Referring to Figs. 3 and 4, the bushing 2 has an annu lar projection 2against which rests-the inner end of the In this modification the innerwall 15 of of the coupling is tapered to conform with the conicallyflanged portion of the strainer 7 and the spiim'eret 11. thuseliminating the necessity for the rings 8 and 12 respectivelyas shown inFig. 1. The packing rings or washers may be dispensed with in this'modification since the inner ends of the rings 6 and 10 present asurface against which the viscous fluid may act under pres sure. Byvirtue of this latter construction the viscous fluid not onlyeauses thestrainer and spinneret to clamp themselves more securely in position. asdescribed in Fig. l, but causes an additional clumping actiorrhy forcingthe rings 6 and 10 respectively, further into the flanges.

In the modification illustrated in Figs. 5 and 6, I have provided astructure in which the strainer may be made considerably larger thanthat illustrated in the preceding figures. in this case the coupling 3is enlarged at its inner end and fitted over the large bushing 2". Onaccount 05 thisconstrnction the strainer might not re duce thepressureoi the viscose between the strainer and the spinneret sufficiently todispense with mechanical means for holding the strainer tightly againstthe inner tapering surface of thecoupling 3 of the spinninghead. I.therefore preferto screw the bushing 2 down againstthe inner ends of thering 6 and strainer 7 to force the flange of the strainer tightlyagainst the. inner tapering Wall of the coupling. Under such conditions,'however, even with this construction the spinncret might be held in itsproper position by the pressureoi the viscosealone as has'beenheretofore explained Froni the above description i-t-will be apparentthat I have provided a structure .in which both the strainer and thespinneret may be made of very light or thin ma.- terial which can bedrilled or pnnched'to provide them :with suitable perforations, but atthe same time thesaine are so-mounted within the spinning head that theyare pie vented from collapsing-or varying substantially from theiroriginal form, notwithstanding. the high pres sure to whiehthey'aresubjected and the tender It is 0i course to be understood that in orderto pre- 'r v the viscose to force the-same outwardly through the con-'tractcd opening in the cadet the head.

ing the spinneret the holes or perforations in the strainer mustncccssarilybo slightly smaller than those in the spinnerct.
